Sorry about the lack of updates, been super busy between work, school and the lady. The wet sleeves have all been bored to 3.685", leaving just enough material to hone the walls after the cylinders are pressed into the block. Need to turn down the outside diameters to final adjusted specs, but that shouldn't take more than a couple days of class. Was able to let my instructor give me free reign of the shop for my last semester, so should really be able to crank on the truck a lot more now.
Have also created copper gaskets .021" thick to go between the block and spacers to seal coolant/oil passages as the head gasket will be on the wrong side of the spacer and didn't feel like mangling a second set of gaskets by cutting out the fire ring. Plus it should increase thermal transfer away from the spacers and heads. The second picture shows more clearly what I mean.
Tomorrow morning the heads get resurfaced. The aluminum plate attached to them allows me to flip the head and easily clamp it to the mill table. (PS, stupid simple to make, just a piece of 1/2" thick 6061 bolted along the valve cover rail and another bolted to the rocker shaft holes)
An finally the spacer. Had the local steel distributor laser cut some 3/4" HRS plate to rough dimensions and make starter bores on 4.760" centers. The milling is going to take a long time, but it's finally getting to the point where I get to shop around for a good block machinist.
